Sensor assembly for equipment for aiding the traceability of agri-food products

Sensor assembly for equipment for aiding the traceability of agri-food products, comprising:

• a casing having a first face and a second face opposite to one another, the first face being configured to be coupled to a planar structure;
• a weighing device, arranged so as to respond to a load on the second face of the casing;
• an inclinometer, rigidly attached to the casing;
• an accelerometer, rigidly attached to the casing and configured to supply an acceleration signal indicative of accelerations along an axis perpendicular to the first face of the casing;
• a processing unit configured to determine a measured weight bearing on the weighing device based on load signals supplied by the weighing device, on an inclination signal supplied by the inclinometer and on the acceleration signal supplied by the accelerometer;
• and
• a communication module configured for connection to an access point of a data network, wherein the processing unit is configured to communicate with external devices through the communication module;
• wherein the processing unit is configured to determine the measured weight based on current values of the load signals and the inclination signal, and based on a first calculation mode when the acceleration signal supplied by the accelerometer lies within a control amplitude band, and to determine the measured weight based on values of the load signals and the inclination signal, and based on a second calculation mode;
• and
• wherein the processing unit is configured to determine the measured weight based on the second calculation mode from values of the acceleration signal and the inclination signal, at least in part temporally not corresponding to a cut-off interval defined by a time interval in which the acceleration signal exceeds the control amplitude band, and to store time series of the load signals, the acceleration signal and the inclination signal, and to associate timestamps with the load signals, the measured weight, the acceleration signal and the inclination signal.
